Using a water butt comes with many benefits. It not only provides you with an ideal source of water for your plants, but also reduces your carbon footprint and could even save you money.
A water butt is a very simple device but an incredibly useful one. By connecting a water butt to the downpipe of your house, you can easily store the rainwater that gathers in your drainpipes and use it to water your plants amongst other things.
Features to consider when buying a water butt include –
- Its size – Size is always going to be an important considering when buying a water butt. Some hold much more water than others, so you should think about how much you’re likely to use and choose accordingly.
- Materials used – The majority of water butts are made from plastic, which is ideal since it’s easy to clean and copes with harsh weather well. If you prefer though, there are models that are made from other materials, including wood, stone and clay.
- Style and colour – Your water butt will be something that’s going to be outside your house for a long time, so even if it’s not on display, you still want to be sure that you’re happy with its appearance.

If you’re looking for a water butt that’s unique looking, then the Sankey 150L Beehive Water Butt certainly fits the bill. Shaped like a beehive and with a ceramic appearance to the exterior, it would fit in well in most gardens, especially if you have a lot of stone or ceramic plant pots.

The Benefits of Owning a Water Butt
Owning a water butt comes with some unique benefits. These include –
Easy to fit
Water butts are very easy to set up and don’t really require any special DIY skills. You also don’t need to worry about providing power as you do with a lot of other gardening equipment.
Suitable for most gardens
A lot of gardening equipment requires you to have a decent-sized garden. This isn’t a problem with a water butt since you’re able to use them even in smaller gardens, providing there is a downpipe to connect it to.
You can also get water butts in many different shapes and sizes, so if you’re looking for something that’s less conspicuous that won’t take up too much space, this won’t be a problem.
A convenient supply of water
The convenience of having a plentiful supply of rainwater to use in your garden is something you’ll wonder how you did without once you get used to having it there. Getting water from a water butt is incredibly easy and the fact that it’s already outdoors saves you from having to keep making trips in and out of the house.
Rainwater is ideal for plants
Another great thing about having a water butt is that it provides you with plenty of rainwater to use on your plants. Rainwater is ideal for plants since it’s free of any chemicals that are in tap water and because it’s at an ideal pH level, being slightly acidic.
If you’re on a water meter, then recycling rainwater is a great way to save money. The initial investment in a water butt is far outweighed by what you could save in the long term, especially during the summer months when you need to water your plants more often.
Using a water butt is a great way to reduce your carbon footprint. Getting water from a tap, it first needs to be treated and pumped, which requires a lot of energy. Making use of a water butt is a much more environmentally friendly way of getting water to use for your garden.
How To Fit A Water Butt
The first thing you need to do is position your water butt so it’s close enough to the downpipe of your house. The water butt shouldn’t be any further than 50cm from the downpipe. You should also screw the provided tap into the hole at the base of the unit.
Once the water butt is in position, you then need to drill a hole in the top of it using a hole saw. Some water butts come pre-drilled, so you can skip this step if that’s the case. After you’ve drilled the hole you should attach the hose connecter to it.
You’ll now need to remove a section of your downpipe so it can be attached to your water butt. Mark a section of the downpipe that’s level with the hole you drilled in the water butt. The size of the section you need to cut will vary depending on the model, so be sure to check the instructions that came with your water butt.
After you’ve cut the section from your downpipe, you may need to cut the diverter lid, so it fits your downpipe. Then attach the connector pipe to the downpipe, making sure it’s level with the hole at the top of the water butt.
The final step is to cut the pipe so it’s the right length and then attach the water butt to the downpipe.
Once your water butt is set up, all you need to do is use the tap at the base to get water and providing it’s fitted properly, it should last you for many years.
